The [http://eeepc.asus.com/global/ Eee PC] has really taken the sub-compact pc market by storm.  Although the bundled linux installation is interesting, Fedora is more our style.  This page should contain all the needed quirks and notes needed to run Fedora perfectly on the Eee PC.
Using USB pendrive (at least 1 GB) take a look at the [[FedoraLiveCD/USBHowTo| USB Howto page]]


== News ==
Using the regular installation DVD may be problematic when putting it on USB flash drives. Use the livecd versions.

* '''2008-06-10''' New resume from suspend wireless FIX: handles both Wifi ON and OFF...so no problems with madwifi not loaded
* '''2008-06-10''' New feature: Webcam ON/OFF switch in Fn+F6!
* '''2008-06-10''' Fixed resume from suspend backlight issue, look at the new fix
* '''2008-06-10''' Fixed fn Volume keys. Update your script

* '''2008-02-14''' [http://www.redhatmagazine.com/2008/02/14/fedora-eee-pc-eeedora/ Red Hat Magazine: Fedora + Eee PC = Eeedora]


== ACPI State of play==
'''Recommended for resource limited netbooks'''
* Fedora 8: Need to compile the asus_acpi module and use the Asus scripts that handle various functions, Volume Up, Volume Down, Wifi On/Off etc.  Asus also provides their OSD code to notify the user that they have pressed a button.
* Fedora 9: ships with a module called eeepc.ko - read the ACPI support in Fedora 9 to get it work.


http://spins.fedoraproject.org/moblin/


=== Fn Buttons ===
http://spins.fedoraproject.org/xfce/
* Zz/Fn+F1 - Works as expected computer suspends
* Wifi/Fn+F2 - read ACPI support in Fedora 9 to get it work.
* BrtUp/Fn+F3 - Works.  No OSD
* BrtDown/Fn+F4 - Works. No OSD
* SwitchDisplay/Fn+F5 - read ACPI support in Fedora 9 to get it work.
* AP/Fn+F6 - Webcam Switch ON/OFF, read ACPI support in Fedora 9 to get it work. ''AccessPoint Mode?  I don't think we need this.  I was thinking about making this button use xrandr to switch on and off a scrolling Virtual Display. This should help if a large dialog box pops up off screen. (Originally this Fn Key was meant to open the task manager)''
* Mute/Fn+F7 - Works in Fedora 8 with Asus module. read ACPI support in Fedora 9 to get it work.
* VolDown/Fn+F8 - Works in Fedora 8 with Asus module. read ACPI support in Fedora 9 to get it work.
* VolUp/Fn+F9 - Works in Fedora 8 with Asus module. read ACPI support in Fedora 9 to get it work.


=== What does NOT work ===

* Hibernation [https://bugzilla.redhat.com/show_bug.cgi?id=451232 BUG HAS BEEN REPORTED]
* Wireless Button ON/OFF (Fn+F2) [https://bugzilla.redhat.com/show_bug.cgi?id=461329 BUG HAS BEEN REPORTED]
* Making sweet coffee (maybe never be fixed)


=== What Fedora 9 gives you ===
== Custom Spins ==
* Full linux experience (it runs VERY well with stock gnome)
* Acceptable boot time
* Fedora is a lifestyle :) always bleeding edge software for you!


== Installing Fedora ==
To create and customize Fedora (Create Custom "''Spins''") you need to use [[Livemedia-creator-_How_to_create_and_use_a_Live_CD|this guide]]
* Using DVD, you need an external DVD/CD reader
* Using USB pendrive (at least 1 GB) take a look at the [[FedoraLiveCD/USBHowTo| USB Howto page]]
* Using USB pendrive, from Windows [https://fedorahosted.org/liveusb-creator liveusb-creator]

'''Note : for security reasons, these instructions are not suitable on a production or critical environment. So use at your own risk.'''


Also, in new eee PC 901 there is no atheros anymore which was replaced by RT2860 Wireless (rt2860sta can be compiled from sources <http://www.ralinktech.com/ralink/Home/Support/Linux.html>).
Latest stable Fedora release updated fully. Unless the model listed is completely green, expect to be fixing things.

Fn Keys (included wireless switch) o
* Almost working, the Fn+F2 (wireless switch) mostly works; supported by eeepc_laptop kernel module.  May require 'acpi_osi=Linux' to be added to kernel boot parameters for eeepc_laptop module to load. The system doesn't always connect right away when re-enabled by HW switch (~1 minute delay).


=== FN keys and events (fixed) ===
Wireless chipset
* Eee PC 901/1000H wireless chip is Ralink RT2860, which is not supported by current kernel (work on support is in progress, see [http://rt2x00.serialmonkey.com/wiki/index.php/Main_Page rt2400] project page for more details), but there's an open source driver provided by Ralink. RPMFusion has a kmod package with this driver (kmod-rt2860). [https://fedoraproject.org/wiki/OtherRepositories Read this for more details on external repositories].
* 1001p/1005p wireless chip is Atheros AR2427 802.11g WiFi supported by ath9k but needs 2.6.32+ kernel.
* 1015PEM wireless chip is Broadcom BCM4313. Drivers are availible in RPMFusion (package b43-fwcutter or wl kernel module). In recent kernel versions (around 3.1) also brcmsmac became ready and available.

===== Brightness Issues =====
With some Eee PC's, the brightness setting are either too low, or are sometimes a little inconstant or arbitrary (inconsistent on each boot, eg. high to low/completely off).
If you have issues with this, issue this command to fix it:

      echo 1 > /sys/devices/platform/eeepc/camera
        else
            echo 0 > /sys/devices/platform/eeepc/camera
        fi
</pre>
</pre>
(please, do the following step after updating scripts, or new features like the webcam switch!!!)


Make scripts executable:
The <code>80</code> represents the desired range for brightness in hexadecimal, where <code>FF</code> allows to maximum brightness. <code>80</code> is about half and is generally ideal but may need to be tweaked to suit one's need.
<pre>
chmod -v +x /etc/acpi/actions/*
</pre>


== Wireless Drivers ==
Note this is not permanent, so it should be added to rc.local.


=== Eee PC 70x ===
File:<code>/etc/rc.d/rc.local</code>
Eee PC wireless is provided by an Atheros chipset. At this very moment, the only way to make it work on Fedora 9 is using Madwifi patched drivers, or windows driver with ndiswrapper.
<pre>#!/bin/sh

===== Maximize battery life =====
<ol>
<li> Use the integrated HPET timer (saves about 30 CPU wake ups per second)


''GOOD NEWS'': But Fedora '''RAWHIDE kernel natively supports''' EeePC 701 4G wireless hardware. Bad news is still Fn+F2 (wireless on/off) does not work. [https://bugzilla.redhat.com/show_bug.cgi?id=461329 Bug has been reported].
Should be used by default.


<pre>$ cat /sys/devices/system/clocksource/clocksource0/current_clocksource</pre>


You can compile the kernel module or easily install it from an external repository like livna.  After installing livna you can install the driver with the help of [[yum]] from the testing repository by using the <code>--enablerepo=livna-testing</code> option.
This should return 'hpet'


<li> Change IO scheduler to deadline:
Load the module.
<pre># modprobe deadline-iosched</pre>


Sooner or later it would be possible to use the open source version of the ath5k driver for the Atheros chipsets.
Edit /boot/grub/menu.lst


Add 'elevator=deadline' to kernel options.


Here are some [http://bugzilla.livna.org/show_bug.cgi?id=2019 compiled packages] for kernel 2.6.25.4-30.fc9.i686.
<pre>$ cat /sys/block/sda/queue/scheduler</pre>
This should return 'noop [deadline] cfq'


<li>Run powertop as root and do the recommended changes.  Changes do not stick and have to be run again after a reboot.
<pre># dnf install powertop</pre>


Livna repository and Madwifi driver are not officially affiliated or endorsed by the Fedora Project. '''Use them at your own discretion and risk.'''
<li> Disable rarely used services

* [https://fedoraproject.org/wiki/OtherRepositories Read this for more details on externel repositories].
<li>Install Jupiter and Jupiter Support/Eee from [http://sourceforge.net/projects/jupiter/ SourceForge] to add power profiles as well as extra function keys and automatic support for Super Hybrid Engine.


=== Eee PC 901 ===
Download the latest jupiter and jupiter-support-eee RPM packages from SourceForge.
Eee PC 901 wireless chip is Ralink RT2860, which is not supported by current kernel (work on support is in progress), but there's an open source driver provided by Ralink.
RPMFusion has an akmod package with this driver (akmod-rt2860).


Fn+F2 doesn't work here, either.
<pre>sudo dnf clean all
 
sudo dnf install --nogpgcheck /path/to/jupiter*rpm /path/to/jupiter-support-eee*rpm</pre>
== Fixes and solutions to common problems ==
 
=== Shut down fix ===
If your Eee PC does not entirely shutdown, because the snd-hda-intel module cannot be unloaded.
 
<pre>
su -
echo "modprobe -r snd-hda-intel" >> /sbin/halt.local
chmod 755 /sbin/halt.local
</pre>
 
Bug has been reported: https://bugzilla.redhat.com/show_bug.cgi?id=444115
 
=== Wireless resume from suspend fix ===
[https://bugzilla.redhat.com/show_bug.cgi?id=451181 BUG HAS BEEN REPORTED]
Temp workaround:
 
With Madwifi driver, wireless doesn't work when resuming from sleep...but we can fix this issue with this script
(UPDATED! New script, handles sleep with both wifi ON/OFF)
Create the file:
<pre>
su -
gedit /etc/pm/sleep.d/S99wireless
</pre>
and paste this code:
<pre>
#!/bin/sh
WLAN=$(cat /sys/devices/platform/eeepc/wlan)
 
case "$1" in
thaw|resume)
if [[ "$WLAN" = "1" ]]; then
{ ip link set wifi0 up ; } 2>/dev/null
fi
;;
*)
;;
esac
exit $?
</pre>
 
Make the script executable:
<pre>
chmod +x /etc/pm/sleep.d/S99wireless
</pre>
 
=== NetworkManager drop outs fix (Fedora 8 only) ===
''Not necessary in Fedora 9''
* Works well with the Madwifi-NG drivers.  To solve problems with frequents drop outs and communication problems try issuing this command.
<pre>
iwpriv ath0 bgscan 0
</pre>
* Just a quick update on a better way to issue this command on every boot.  Edit your /etc/modprobe.conf and change change your lines for ath0 to look like this.
<pre>
alias ath0 ath_pci
install ath_pci /sbin/modprobe --first-time --ignore-install ath_pci && { /sbin/iwpriv  ath0 bgscan 0 > /dev/null 2>&1 || :; }
</pre>
 
=== Internal Mic not working (fixed) ===
[https://bugzilla.redhat.com/show_bug.cgi?id=451178 Bug has been reported] (fixed in rawhide)
 
Workaround:
 
Double leftclick the volume icon, open preferences and enable e-Mic and e-Mic Boost.
In options select input source: e-Mic
 
(strange, i-mic and e-mic are inverted!)
 
=== TouchPad tap fix ===
To fix the lack of TouchPad tap in Fedora 9, just install the Synaptics package available [http://www.ocf.berkeley.edu/~bobk/packages/ here]
 
<pre>rpm -ihv http://www.ocf.berkeley.edu/~bobk/packages/synaptics-0.14.6-8.1.fc9.i386.rpm</pre>
 
''Old solution'' (I think this is for Fedora 8, please specify)
To enable the touchpad tapping, make your /etc/X11/xorg.conf look [http://forums.fedoraforum.org/showpost.php?p=1012733&postcount=16 like this] .
 
=== No backlight on resume from suspend (fixed) ===
[https://bugzilla.redhat.com/show_bug.cgi?id=451180 Bug has been reported] (fixed in rawhide)
 
This bug has been fixed in kernel 2.6.26.
 
The temporany workaround isn't working anymore, so let's wait for the new kernel release in fedora 9
 
=== Screen is off after resume from suspend/hibernate (Eee PC 901) ===
A different bug than the above, but adding --quirk-dpms-on to pm-suspend/pm-hibernate helps. Adding --store-quirks-as-fdi makes it permanent.
 
Note: upgrading to BIOS 1603 seems to have removed the need for this quirk.
 
See [https://bugzilla.redhat.com/show_bug.cgi?id=468271 bug 468271].
 
== Hints and alternative software ==
 
=== Openbox as window manager ===
Do yourself a favor and install [http://icculus.org/openbox/index.php/Main_Page Openbox] .
<pre>
yum -y install openbox obconf
</pre>


After installation you will need to choose openbox as your new window manager. If you are running gdm click on the session button and choose Gnome/Openbox.  If you have an .xinitrc that is run at log in you can add, openbox, openbox-session or openbox-gnome-session to it.
</ol>


Why?
===== Maximize performance =====
* This Window Manager is FAST!!!
* The decorations are very small and simple.
* By default Openbox trys to shrink windows to fit the viewable screen
* Did I say this how fast this WM is?


=== Firefox 3, really a cpu eater ===
Use Epiphany instead of Firefox 3... it's slim (written using the GTK libs) fast as Firefox 3, same compatibility (uses gecko as rendering engine).


=== Webcam ===
<ol>
The driver for the built-in webcam for the Eee PC 900 serie is installed with Fedora 9, you just have to load it.
<li> Noatime for hard drive (reduces writes to disk)


modprobe uvcvideo
<pre>nano /etc/fstab</pre>


To get the same webcam application like the original OS of the Eee PC, install a small tool named <code>ucview</code>
Add ",noatime,nodiratime" after "defaults" for all ext2,ext3,ext4 partitions.


yum -y install ucview
<li>Remove Pulseaudio (when playing music or watching video pulseaudio can raise CPU usage high)


<pre># dnf remove pulseaudio</pre>


== Kickstart files ==
Switch audio preferences to ALSA.  Video players also need to be changed to ALSA in audio properties.


With a kickstart file you can ease the process of installing Fedora on your Eee PC.
<li>Turn off unnecessary services on start up.


* The [http://herlo.fedorapeople.org/files/f9eeepc.ks kickstart file] from [[User:herlo| Clint Savage]] for Live media
Should usually be found in Preferences -> Startup

Installing Fedora LiveCD from USB flash drive

Using USB pendrive (at least 1 GB) take a look at the USB Howto page

Using the regular installation DVD may be problematic when putting it on USB flash drives. Use the livecd versions.

Recommended for resource limited netbooks

Green: works
Yellow: should eventually work
Red: non-free drivers or serious hardware support problems

Eee PC 90x/1000H/1005HA/1005PE/1015PEM/1015PN Series

The XXXp models (like the 1005p) are based on newer Pine Trail platforms. Issues may arise as newer models are released.

Fn Keys (included wireless switch) o

  • Almost working, the Fn+F2 (wireless switch) mostly works; supported by eeepc_laptop kernel module. May require 'acpi_osi=Linux' to be added to kernel boot parameters for eeepc_laptop module to load. The system doesn't always connect right away when re-enabled by HW switch (~1 minute delay).

Wireless chipset

  • Eee PC 901/1000H wireless chip is Ralink RT2860, which is not supported by current kernel (work on support is in progress, see rt2400 project page for more details), but there's an open source driver provided by Ralink. RPMFusion has a kmod package with this driver (kmod-rt2860). Read this for more details on external repositories.
  • 1001p/1005p wireless chip is Atheros AR2427 802.11g WiFi supported by ath9k but needs 2.6.32+ kernel.
  • 1015PEM wireless chip is Broadcom BCM4313. Drivers are availible in RPMFusion (package b43-fwcutter or wl kernel module). In recent kernel versions (around 3.1) also brcmsmac became ready and available.

Video Card ION (1015PN)

  • Works properly with nouveau driver
  • To be able to switch between video cards, follow this tutorial.

Issues

  • Fn Key to disable wireless also disables eth0 [fix: what model?]
  • Screen is off after resume from suspend/hibernate (Eee PC 901) - upgrade to BIOS 1603

Eee PC 1101 Series

The 1101 series has a 11.6" screen and a dual-core 1.33Ghz Atom Z250 processor.

Integrated Intel GMA 500 video chipset

Fn Keys with issues

  • Fn+F3 touchpad: no
  • Fn+F4 screen resolution: no
  • Fn+F5 brightness down: no
  • Fn+F6 brightness up: no
  • Fn+F8 external monitor: ?

Wireless chipset

  • Atheros AR9285 wireless chip supported natively by ath5k kernel module. Unfortunately, the WiFi doesn't resume after suspend.

Eee PC 1201 Series

The 1201 series has a 12.1" screen and a dual-core 1.6GHz Atom 330 processor.

Eee PC 1201HAB

Intel Atom Z520 running at 1.33Ghz at default settings

  • Works well using jupiter to automate SHE "overclocking" to boost to 1.7Ghz

Intel GMA 500

  • Works out of the box on beefy miracle
Eee PC 1201N

The nVidia ION model.

Integrated nVidia GeForce 9400M video chipset

  • supported by nouveau driver, may have problems with suspend
  • supported by proprietary nvidia driver

Fn Keys

  • display-related keys work
  • sound-related are not supported by KDE system
  • rfkill doesn't work
  • touchpad disabler doesn't work.

Wireless chipset

  • not supported by default, no packages in rpmfusion, no drivers in staging tree. This is a Realtek RTL8192SE chip, incompatible with RTL8192E and RTL8192SU drivers already in staging.
  • vendor-supplied free drivers may or may not work, depending on your kernel version and system CPU architecture
  • you may have luck with a rtl8192se_linux_2.6.0010.1116.2009 driver on 2.6.31.5 or 2.6.31.9 kernel on x86_64 architecture.

Fixes and solutions to common problems

FN keys not working

eeepc_laptop is not loaded. Edit /boot/grub/menu.lst. Add 'acpi_osi=Linux' to the kernel options. 

# lsmod|grep eee

eeepc_laptop should be listed in the results.


Hiding the battery broken alert

This fixes the annoying battery broken alert reported by gnome-power-manager on login. That's a known bug 

$ gconftool-2 --type bool --set /apps/gnome-power-manager/notify/low_capacity 0
Brightness Issues

With some Eee PC's, the brightness setting are either too low, or are sometimes a little inconstant or arbitrary (inconsistent on each boot, eg. high to low/completely off). If you have issues with this, issue this command to fix it: 

# setpci -s 00:02.0 f4.b=80

The 80 represents the desired range for brightness in hexadecimal, where FF allows to maximum brightness. 80 is about half and is generally ideal but may need to be tweaked to suit one's need.

Note this is not permanent, so it should be added to rc.local.

File:/etc/rc.d/rc.local 

#!/bin/sh

...

setpci -s 00:02.0 f4.b=80

Hints and alternative software

Maximize battery life
  1. Use the integrated HPET timer (saves about 30 CPU wake ups per second) Should be used by default. 
    $ cat /sys/devices/system/clocksource/clocksource0/current_clocksource

    This should return 'hpet'

  2. Change IO scheduler to deadline: Load the module. 
    # modprobe deadline-iosched

    Edit /boot/grub/menu.lst

    Add 'elevator=deadline' to kernel options. 

    $ cat /sys/block/sda/queue/scheduler

    This should return 'noop [deadline] cfq'

  3. Run powertop as root and do the recommended changes. Changes do not stick and have to be run again after a reboot. 
    # dnf install powertop
  4. Disable rarely used services 
    # for s in abrtd atd auditd avahi-daemon ip6tables iscsi iscsid mdmonitor portreserve livesys livesys-late; do echo "chkconfig $s off"; chkconfig $s off; done
  5. Install Jupiter and Jupiter Support/Eee from SourceForge to add power profiles as well as extra function keys and automatic support for Super Hybrid Engine. Download the latest jupiter and jupiter-support-eee RPM packages from SourceForge. 
    sudo dnf clean all
sudo dnf install --nogpgcheck /path/to/jupiter*rpm /path/to/jupiter-support-eee*rpm
Maximize performance
  1. Noatime for hard drive (reduces writes to disk) 
    nano /etc/fstab

    Add ",noatime,nodiratime" after "defaults" for all ext2,ext3,ext4 partitions.

  2. Remove Pulseaudio (when playing music or watching video pulseaudio can raise CPU usage high) 
    # dnf remove pulseaudio

    Switch audio preferences to ALSA. Video players also need to be changed to ALSA in audio properties.

  3. Turn off unnecessary services on start up. Should usually be found in Preferences -> Startup
